Yes, exactly, its the linear bearings that can be at different locations and force therefore the board to different positions, those are the ones that i am interested in! On Saturday, June 11, 2016 at 6:49:34 PM UTC+2, Jason Moore wrote: > > If the blue dots are fixed on the board, doesn't the l

If the blue dots are fixed on the board, doesn't the linear bearings remove all degrees of freedom? I don't see how this thing can move. Jason moorepants.info +01 530-601-9791 On Sat, Jun 11, 2016 at 8:57 AM, wrote: > They describe the location of the board (the blue rectangle) in relation > t

Actually the question is, in some sense, wrong. What you should be doing (I hope you will consider this as constructive) is look for integrands of the form constant* f(u)^p*du. That includes 3*(4+5*x)^6but also 7*(8+9*x^2)^p * x and even (1+2*sin(x))^p*cos(x). this is one part of a "deri

They describe the location of the board (the blue rectangle) in relation to its "normal" position by a rotation about an angle of phi and a translation of x and y. On Saturday, June 11, 2016 at 5:40:26 PM UTC+2, Jason Moore wrote: > > Where are phi, x, y on the diagram? > > > Jason > moorepant

Physically, the rows of A are three points fixed on a movable board. These points run freely in three linear bearings which are placed on a fixed base. The linear bearings are described in hesse normal form in the rows of matrix C. The robust motion matrix B is the transformation which transf

Physically what are all the matrices. Do A and C also describe rotations. Please give the actual physics problem as well as the resulting math. On Sat, Jun 11, 2016 at 6:37 AM, wrote: > My description was a little compressed, so i had to clean up the code to > match my description again ... > T
